Sample 1: Basic Usage

The Text property specifies the text to be rendered.

page.dothtml
ViewModel.cs

<bp:TextView Text="{value: ContactInfo}" />
<bp:TextView Text="{value: Paragraphs}" />

using DotVVM.Framework.ViewModel;

namespace DotvvmWeb.Views.Docs.Controls.businesspack.TextView.sample1
{
    public class ViewModel : DotvvmViewModelBase
    {
        public string ContactInfo { get; set; } = "RIGANTI s.r.o.\nSokolovsk� 352/215\[email protected]\nwww.dotvvm.com";

        public string Paragraphs { get; set; } = @"TextView

    }
}

Sample 2: Server Rendering

To render the HTML directly in the page without the need to transfer it in the viewmodel, you can use the RenderSettings.Mode to turn on the server rendering.

This helps especially the search engines to index the contents of the page. You can read more in the Server-Side HTML Generation and SEO chapter.

page.dothtml
ViewModel.cs

<bp:TextView Text="{value: ContactInfo}"
             RenderSettings.Mode="Client" />

<br />

<bp:TextView Text="{value: ContactInfo}"
             RenderSettings.Mode="Server" />

using DotVVM.Framework.ViewModel;

namespace DotvvmWeb.Views.Docs.Controls.businesspack.TextView.sample2
{
    public class ViewModel : DotvvmViewModelBase
    {
        public string ContactInfo { get; set; } = @"RIGANTI s.r.o.
                                                    Sokolovsk� 352/215
                                                    [email protected]
                                                    www.dotvvm.com";
    }
}

Sample 3: Link Target

The URLs and e-mail addresses in the text are detected automatically.

The HyperlinkTarget property specifies the target attribute value in the links generated by the control. You can use it to open the pages in a new window, for example.

page.dothtml

<bp:TextView HyperlinkTarget="_blank">
    [email protected]
